Tuff-Luff Aero represents a major evolution of slotted headstay systems. Its unique aerodynamic shape provides at least 9% more lift. Faster wind reattachment to the sail with less turbulence is also a benefit of the patented teardrop shape. If you have the need for speed, you have a need for Tull Luff Aero. Engineering for high impacts eliminates the need for bumpersCustom polycarbonate material is lighter, stronger and more durable than comparative systems.
